Shoving it in irq_cpustat is what is presently done by at least mn10300, x86, and xtensa. sparc chose stashing it in its cpuinfo struct, but then also has a meaningful per-cpu storage area. If you have any better ideas I'll certainly consider moving it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
